Compared with the prior art, the present invention has the following beneficial effects:

1. During use, when the temperature sensor detects that the cooling effect of the water-cooling component in combination with the air-cooling component is still poor, the controller controls the start of the hydraulic rod. When the hydraulic rod is extended, it drives the extrusion block forward, so that the extrusion block and the U-shaped cavity press the hose into an arc-shaped flat sheet. The liquid flow rate can be adjusted and closed during the pushing process. Liquid ethylene glycol is filled in the liquid tank. The state of ethylene glycol is liquid and will flow into the buffer tube through the connecting pipe. The buffer tube will slow down the flow rate of ethylene glycol and can flow into the water tank through the hose. When ethylene glycol and water are mixed, an ethylene glycol aqueous solution is formed. The ethylene glycol aqueous solution has a lower freezing point and a higher boiling point, and can quickly reduce the temperature of objects at a lower temperature. At this time, the liquid flowing in the pipe of the water-cooling component is an ethylene glycol aqueous solution with a better cooling effect, so that the dual cooling device is more effective in cooling the hydraulic system of the excavator loader.

2. When in use, the temperature sensor monitors the temperature rise of the hydraulic system and transmits the temperature rise signal to the controller. After receiving the signal, the controller controls the start of the liquid pump, and the water inlet pipe draws the water inside the water tank and transports it from the water outlet pipe to the arc-shaped cooling bin connected to it. Under the connection of multiple flow pipes, the water drawn out of the water tank will be quickly transported to the two arc-shaped cooling bins, and then flow back to the water tank from the delivery pipe. When the water circulates, it can take away the heat between the two arc-shaped cooling bins, and the multiple heat-conducting fins are made of metal copper, which is more conducive to absorbing heat to the surface of the arc-shaped cooling bin. With the continuous circulation of water, the effect of cooling is achieved. When the water flows back to the water tank from the delivery pipe, it will pass through the flow meter body. The flow meter body determines the current water circulation speed and sets the degree in advance in the controller. When the temperature monitored by the temperature sensor is higher, the controller controls the speed of the liquid pump to be faster, and vice versa. The speed of the liquid pump is slower.

3. When in use, by starting the servo motor, the output shaft of the servo motor drives the I-beam shaft to rotate in the limit block. The limit block supports the I-beam shaft and can prevent the I-beam shaft from tilting during rotation. Since the I-beam shaft is connected to the rotating shaft, the rotating shaft rotates simultaneously with the I-beam shaft, thereby causing the fan blades to rotate to generate wind, which can accelerate cooling by blowing the wind toward the position of the arc-shaped cooling bin.

4. When in use, adjust the distance between the two arc-shaped cooling bins according to the volume of the hydraulic system to be cooled, so that the two arc-shaped cooling bins can fit on the outside of the equipment to be cooled. When adjusting, turn the adjusting handle to drive the threaded rod to rotate inside the threaded sleeve. The two threaded sleeves and the two threaded rods are limited to each other to achieve position adjustment of the two arc-shaped cooling bins.

As shown in FIGS. 1-3 and 6 , a servo motor 206 is provided near one side of the top of the support plate 205, a limit block 207 is fixedly installed near the other side of the top of the support plate 205, an I-shaped shaft 210 is rotatably embedded inside the limit block 207, an output shaft of the servo motor 206 is fixedly connected to one side of the I-shaped shaft 210, a rotating shaft 211 is installed on the other side of the I-shaped shaft 210, a plurality of fan blades 212 are provided on the outer surface of the rotating shaft 211, a reinforcing plate 209 is fixedly connected to one side of the support plate 205, and a protective cover 20 is fixedly connected to the outer surface of the reinforcing plate 209. 8. By starting the servo motor 206, the output shaft of the servo motor 206 can drive the I-shaft 210 to rotate in the limit block 207. The limit block 207 supports the I-shaft 210 and prevents the I-shaft 210 from tilting during the rotation. Since the I-shaft 210 is connected to the rotating shaft 211, the rotating shaft 211 rotates simultaneously with the I-shaft 210, thereby causing the fan blades 212 to rotate and generate wind. The wind blows toward the position of the arc-shaped cooling bin 301, which can accelerate cooling.

The method of using and the working principle of the present device are as follows: when in use, first, the mounting plate 103, the fixing plate 109, the bottom plate 110, and the fixing frame 111 form an integral mounting frame as shown in FIG7, which can complete the installation of the controller 107 and the liquid pump 113 and the placement of the water tank 101, and then the hydraulic equipment of the excavator loader that needs to be cooled is arranged between the two arc-shaped cooling bins 301. The two arc-shaped cooling bins 301 are symmetrically arranged. By using the support clamping plate 6 to clamp the threaded sleeve 307, the arc-shaped cooling bins 301 are supported by the support frame 4. According to the volume of the equipment to be cooled, the distance between the two arc-shaped cooling bins 301 can be adjusted so that the two arc-shaped cooling bins 301 can be attached to the outside of the equipment to be cooled. When adjusting, by rotating the adjusting handle 308, the adjusting handle 308 drives the threaded rod 309 to rotate inside the threaded sleeve 307. The two threaded sleeves 307 and the two threaded rods 309 are mutually limited, so as to realize the two arc-shaped cooling bins 30 1, wherein the temperature sensor 202, the flow meter body 104, the liquid pump 113, and the hydraulic rod 122 are all electrically connected to the controller 107, and are all electrically connected to the external power supply. The temperature sensor 202 detects the temperature rise of the hydraulic system, and transmits the temperature rise signal to the controller 107. After receiving the signal, the controller 107 controls the start of the liquid pump 113, and the water inlet pipe 114 pumps the water inside the water tank 101 out. Under the pressurization of the liquid pump 113, the water in the water tank 101 is pumped out from the liquid pump 113. The water outlet pipe 303 is transported to the arc-shaped cooling chamber 301 connected thereto. With the connection of multiple circulation pipes 305, the water drawn out of the water tank 101 will be quickly transported to the two arc-shaped cooling chambers 301. When the two arc-shaped cooling chambers 301 are filled with water, the water flows back to the water tank 101 from the delivery pipe 304. The water can take away the heat between the two arc-shaped cooling chambers 301 when circulating. The multiple heat-conducting fins 302 are made of metal copper, which is more conducive to absorbing heat into the arc-shaped cooling chambers. The surface of 301 is cooled and cooled as the water circulates continuously. At this time, when the water flows back to the water tank 101 from the delivery pipe 304, it will pass through the flow meter body 104. The flow meter body 104 determines the current water circulation speed, and the controller 107 sets the degree in advance. When the temperature detected by the temperature sensor 202 is higher, the controller 107 controls the speed of the liquid pump 113 to be faster, and vice versa. The speed of the liquid pump 113 is slower. At the same time, by starting the servo motor 206, the output shaft of the servo motor 206 is made so that the output shaft of the servo motor 206 can drive the I-axis 210 to rotate in the limit block 207. The limit block 207 supports the I-axis 210 and can prevent the I-axis 210 from tilting during the rotation. Since the I-axis 210 is connected to the rotating shaft 211, the rotating shaft 211 rotates simultaneously with the I-axis 210, so that the fan blades 212 rotate to generate wind, and the wind blows to the position of the arc-shaped cooling bin 301 to accelerate the cooling. In addition, when the temperature sensor 202 detects that the cooling effect of the water-cooling component 3 in combination with the air-cooling component 2 is still poor, the controller 107 controls the hydraulic rod 122 to start. When the hydraulic rod 122 is extended, the extrusion block 124 is driven to push forward, so that the extrusion block 124 and the U-shaped cavity 119 press the hose 125 into an arc-shaped flat sheet. The liquid flow rate can be adjusted during the pushing process. Ethylene glycol is loaded into the liquid tank 102. The state of ethylene glycol is liquid and will flow into the buffer tube 126 through the connecting pipe 127. The buffer tube 126 will make the ethylene glycol flow slowly and can flow into the water tank 101 through the hose 125. When ethylene glycol and water are mixed, an ethylene glycol aqueous solution is formed. The ethylene glycol aqueous solution has a lower freezing point and a higher boiling point, and can quickly reduce the temperature of an object at a lower temperature. At this time, the liquid flowing in the pipeline of the water-cooling component 3 is an ethylene glycol aqueous solution with a better cooling effect, so that the dual cooling device is more effective in cooling the hydraulic system of the excavator loader.

Among them, the flow meter body 104 is an instrument for measuring fluid flow, and its structural composition usually includes parts such as a fluid inlet, a fluid outlet, a fluid channel, a sensor and a display device. A common example is a turbine flow meter. Its working principle is that the fluid enters the fluid channel through the fluid inlet, and the flow of the fluid causes the rotor equipped with an impeller to start rotating. The sensor detects the rotation speed of the rotor and converts it into an electrical signal. After the electrical signal is processed, it is displayed through a display device to indicate the flow rate of the fluid. In addition, the temperature sensor 202 is a device for measuring the temperature of an object. Its structural composition usually includes parts such as a temperature sensing element, a signal processing circuit and an output device. A common temperature sensor 202 has a thermistor, and its working principle is that a thermistor is a component whose resistance changes with temperature. When the temperature changes, the resistance value of the thermistor will also change accordingly. The signal processing circuit converts the resistance value of the thermistor into an electrical signal related to the temperature. After the electrical signal is processed, it is displayed through an output device to indicate the temperature of the object.

The model is selected according to the actual use, so the control method and wiring layout of the flow meter body 104, controller 107, liquid pump 113, hydraulic rod 122, temperature sensor 202 and servo motor 206 will not be explained in detail.
